SNMP Device Locator Limitations

The following are the limitations when using the SNMP Device Locator.

  • On the Juniper JUNOS Base OS 12.3 the SNMP ports are in the 500s, setting the port names will be extremely tedious.
  • The Device Locator uses two specific SNMP tables to collect information from switches/routers. If neither of tables below are available, the program will not be able to execute. The two tables are:

  1. dot1qTpFdbTable (1.3.6.1.2.1.17.7.1.2.2), where the entries being used are:

  • dot1qTpFdbPort (1.3.6.1.2.1.17.7.1.2.2.1.2)

  • dot1qTpFdbStatus (1.3.6.1.2.1.17.7.1.2.2.1.3)

  1. dot1dTpFdbTable (1.3.6.1.2.1.17.4.3), where the entries being used are:

  • dot1dTpFdbPort (1.3.6.1.2.1.17.4.3.1.2)

  • dot1dTpFdbStatus (1.3.6.1.2.1.17.4.3.1.2)

  • The behavior of the program is not guaranteed when using authentication protocols HMAC192SHA256 and HMAC384SHA512.
